The performance of wind turbine is greatly affected by aerofoil performance, so that it is important subject for developing a new exclusive wind turbine blade to elucidate an aerodynamic characteristic on rotating blade. This report describes two experimental test : (i) Comparison of field test and wind tunnel test about pressure distribution on blade surface. (ii) Visualization at suction surface of measurement section of test blade. In this report, cross flow is focused on analysis of flow behavior, which is an element of unsteady flow and affects the blade performance. From obtained results, we considered relation between pressure distribution and cross flow.
